HAY-STACKER.

Specification of Letters Patent.

Patented Mar. 25, 1913.

Application filed September 6, 1912. Serial No. 718,954.

T 0 all whom it may concern Be it known that I, Jesse M. ORoAN, acitizen of the United States, residing at Beatrice, in the county ofGage, State of Nebraska, have invented certain new and usefulImprovements in Hay-Stackers; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to hay loaders and has for an object to provide adevice of this character having a plurality of rakes mounted forsimultaneous reciprocating and oscillating movement.-

A further object of the invention is to provide a hay loader having anendless elevator which carries the rakes, a single driving shaft beingemployed to simultaneously actuate the rakes and endless carrier.

With the above objects in view the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claim.

In the accompanying drawings forming part of this specification :Figure1 is a side elevation of the device. Fig. 2 is a plan view of thedevice. Fig. 3 is a rear end elevation of the device. Fig. 4 is alongitudinal sectional view through the device. Fig.

5 is a vertical sectional view taken on the line 55 Fig. 1. Fig. 6 is across sectional view taken on the line 66 Fig. 1.

Referring now to the drawings in which like characters of referencedesignate similar parts, 10 designates a pair of skids which areconnected by cross bars 11. A shaft 12 is mounted for rotation inbearings 13 arranged on the top faces of the skids and is equipped atone end with a loose belt pulley l4 and a fixed driving pulley 15. Anelevator is pivoted on the shaft and comprises side boards 16 which areconnected by cross bars 17 upon which are secured a plurality of boards18 that extend longitudinally of the side boards and form a bottom. Aroller 19 is journaled at the upper end of the bottom in the sideboards, and upon the shaft 12 is fixed a pair of spaced belt pulleys 20.A plurality of flights 21 are terminally connected at their ends byendless belts 22 which are trained over the roller 19 and belt pulleys20, the endless icarrier thus formed encircling the bottom of theelevator.

For raising and lowering the elevator, a pair of uprights 23 are securedto the skids and are braced by inclined braces 24. A shaft 25 isterminally journaled at the upper ends of the uprights and is equippedwith a spacing sleeve26 between the uprights. Each upright is formed oftwo timbers 27 and 28, and between these timbers a pulley 29 is fixed tothe shaft 25. A pair of supporting cables 30 are trained over thepulleys 29 and are each terminally connected at one end to the sideboards of the elevator, and are each connected at the.

opposite end to a shaft 31 which is journaled in bearings 32 fixed tothe skids. The cables may be wound or unwound from this shaft to raiseor lower the elevator, by rotating the shaft with a crank handle orotherwise. A ratchet wheel 33 is fixed to the shaft, and a gravity pawl34 carried by one of the skids engages the ratchet wheel to lock theshaft stationary.

A pair of posts 35 are fixed to the side boards of the elevator near thelower or intake end of the latter and are connected at their upper endsby a cross bar 36. Each of the posts is provided at the upper end with alongitudinal slot 37 the edges of which are beveled as shown at 38. Abearing block 39 is removably mounted in each slot by means of pins 40passed through the posts andinto the block. Each bearing block isprovided on the corners with guide flanges 41 which fit the beveledcorners of the related slot and retain the block in position. A rod 42is fixed at the ends in the bearing blocks 39 and forms a guide for therakes which will now be described.

A pair of posts 43 are secured to the side boards of the elevator inadvance of the posts 35, and a crank shaft 44 is journaled in the upperends of these posts. The crank shaft is formed with a plurality ofcranks 45 in the present instance three of such cranks beingillustrated. Three rake bars 46 corresponding to the number of cranksare slidably fitted on the guide rod 42, each rake bar being equipped onthe upper edge with an elongated strap bracket 47 which straddles thebar and slidably attaches the bar to the guide rod. Each rake bar isactuated, the rake arms by virtue of being 1 connected to the cranks ofthe crank shaft and slidably fitted upon the guide rod, will besimultaneously reciprocated and oscillated and during such movement willrake straw IOI the like off from a feed board which will be presentlydescribed, on to the elevator which latter will carry the straw on to astack, or loft as may be desired.

The feed board is arranged on the ground in rear of the device abovedescribed and comprises a floor 53 which is supported in inclinedposition by short posts 54 which are arranged at the rear edge of thefloor and project above the same, boards 55 being terminally connectedto the posts above the floor to retain the straw, hay or the like uponthe floor.

What is claimed, is

In a hay stacker, parallel skids, a shaft carried thereby, an elevatorpivoted on said shaft, an endless carrier in said elevator actuated bysaid shaft, a pair of posts rising from said elevator, said post-s beingprovided with slots near their tops, bearing blocks removably secured insaid slots, a guide rod having the ends secured in said blocks, aplurality of rake arms, strap brackets carried by said rake armsstraddling said rod, a second pair of posts carried by said elevator, acrank shaft carried by said posts having the cranks pivotally connectedto the adjacent ends of said rake arms, and means connecting said crankshaft and the first named shaft for simultaneous rotation.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
